more electrons furthur down the group which means stronger van der waals forces exist so higher energy is needed to overcome these forces

What compound has -23 degrees Celsius melting point?
carbon tetrachloride (CCl4)
Why is the boiling point of NaCl higher than sucrose?
Nacl is a salt and forms ions in the solution Na+ Cl- , in other words it has 2 molecules dissociated. On the other hand Sucrose does not dissociate it stays as one mole of sugar. This is why the boiling point of Nacl is higher then Sucrose.
Can KCl and CCl4 form a solution?
KCl and CCl4 do they form solution
What is the formula for carbon tetrachloride?
Carbon tetrachloride has the chemical formula CCl4.
How many atoms of chlorine are in 2.00 moles of CCl4?
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
Would H20 or CCl4 be expected to have a higher melting point?
Boiling point you mean, and H20 has a higher BP
How much viscosity in cf4 ccl4 and cbr4?
ccl4 is more viscous then other two
Is CBr4 more volatile than CCl4?
ch4 is the most volatile
What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
What is the equation of methane and bromine without the presence of sunlight?
The reaction is:3 CCl4 + 4 AlBr3 = 3 CBr4 + 4 AlCl3
What is the molar mass of adrenaline in a solution of 0.64 g of adrenaline in 36.0 g of CCl4 elevates the boiling point by 0.49?
mm=18.604
What is the boiling point of C2H5Cl?
1600 http://chemmaterial.com/chemmaterial/en/products_cacl2.html
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
Does H2O have a higher melting point than CCl4?
Yes. Water melts at 0 ºC. Tetrachloromethane (Carbon tetrachloride) has a melting point of -22 ºC
Why does H2O have a higher melting point than CCl4?
It has to do with intermolecular forces. H2O has an oxygen with two hydrogens coming off of it. This forms two hydrogen bonds, which are much stronger than the London Dispersion Forces in CCl4. (Since CCl4 is non-polar, there are no Dipole-Dipole forces).
Does CI and Br form an ionic bond?
Yes for example with group 1 and group 2 metals. Also they form covalent bonds with non-metals e.g. in CCl4 and CBr4
Does Fe or CCl4 have a higher melting point?
Water molecules, H2O have hydrogen bonding between molecules which means it is a liquid until 100 oC, 212 oF. Carbon tetra chloride/ tetrachloro methane is heavy but boils at 76.8 oC
